M2M Module Installation and Collocation Guidelines
FCC and IC Approval Process for Host Devices
FCC and IC Integrations are covered through two possible approaches.
vi
novatelwireless.com
1) New grant
Labeling: A single ‘New’ FCC ID covers the host and the integrated module.
In this approach the host manufacturer will have the system (host and module) evaluated to
all the applicable FCC requirements. A new FCC ID is obtained to cover this assessment. This
option is the responsibility of the host manufacturer.
2) Class I or a Class II permissive change
Labeling: The Enfora/Novatel Wireless FCC ID appears on the host device.
This section provides module and antenna installation guidelines for host devices to be
authorized for use with the (M2M module here) module through the FCC Class I or Class II
Permissive Change process. As the grantee Enfora/Novatel Wireless is responsible for all
integrations and must be consulted on all regulatory matters involving the GSM0308.
The module was originally granted by the FCC as a single modular approval. The technical
specifications of the integrations will determine the scope of work to cover the integrations.
1) The M2M module can be installed as a standalone transmitter in devices as a Class I
permissive change meeting the following conditions:
a. >20cm separation distance is provided between the M2M transmitting antenna
and the end user at all times.
b. All other intentional radiators within the host device must be evaluated:
i. An antenna location diagram for the host device must be provided,
showing locations of all transmitting antennas and the separation
distance of other transmitting antennas from the M2M antenna
ii. A list of FCC ID’s for all collocated transmitters must be provided.
iii. Datasheets for all collocated transmitting antenna(s) must be
provided, showing manufacturer part number, and peak gain (dBi)
c. The host PCB trace that carries the RF from the module to the external antenna
connector must be evaluated against the design guides. Strict adherence to the
design parameters in the design guides must be observed for a Class I permissive
change to be considered.
d. The antenna gain cannot exceed the following to qualify as a Class I permissive
change:
i. 850MHz: 4.5dBi
vii
novatelwireless.com
ii. 1900MHz: 2.0dBi
e. If the M2M modem is required to provide voice support the design must be
evaluated by Novatel Wireless.
f. The FCC and Industry Canada IDs must be permanently affixed on the exterior of
the notebook or readily accessible under a panel or battery pack of the host device
that cannot be separated from the host device itself.
i. The label must state:
a. This device contains FCC ID: MIVGSM0308
b. This device contains IC: 4160A-GSM0308
g. The user manual/installation guide must give clear instructions regarding the
proper installation and use to ensure compliance with FCC/IC RF Exposure
guidelines, and also include appropriate caution and warning statements and
information
2) The M2M module can be installed as a standalone transmitter in host devices as a Class II
permissive change meeting the following conditions. (Standalone is defined as a single
transmitter transmitting as opposed to 2 or more transmitters transmitting simultaneously.)
a. ≤ 20cm separation distance is provided between the transmitting antenna and
the end user. This will trigger a SAR measurement or evaluation. The OEM
integrator is responsible to design the product to comply with RF exposure, and
must work with Novatel Wireless (the grantee) to satisfy FCC/IC SAR
requirements.
b. If the device does not meet the criteria in item #1 for a Class I permissive change
then additional testing with an application to the FCC will be required.
c. Once the Class II permissive change has been completed the FCC and Industry
Canada IDs must be permanently affixed on the exterior of the notebook or readily
accessible under a panel or battery pack of the host device that cannot be
separated from the host device itself.
i. The label must state:
a. This device contains FCC ID: MIVGSM0308
b. This device contains IC: 4160A-GSM0308
viii
novatelwireless.com
d. The user manual/installation guide must give clear instructions regarding the
proper installation and use to ensure compliance with RF Exposure guidelines.
Note: The host manufacturer is responsible for all standalone regulatory requirements prior to
the integration of the M2M module (i.e. FCC Part 15 for unintentional radiators).

Circuit Protection
The module does not have any protection against ESD events or other excursions that exceed
the specified operating parameters (other than very low level ESD protection within the
module’s integrated circuits).
Generally, you should add ESD protection (typically TVS/Transzorb devices) to all signals that
leave the host board. This includes VBAT/VCC.
You can also add series resistors (typically 47 ) in series with data lines to limit the peak
current during a voltage excursion.
Note: Do not add series resistance to the SIM electrical lines.

As the integrator, it is your responsibility to protect the Enabler IIIG module from
electrical disturbances and excursions that exceed the specified operating
parameters.
Antenna
The GSM0308/GSM0306 module has one RF antenna connection on the module. The
connection is for the GSM section of the module.
Control Connector Signal Functions
Please note that we included the following descriptions to provide hardwarelevel definitions. In some cases, specific lines will have no firmware functionality
implemented. We included information for each hardware-specific feature in the
appropriate section.
Module Power (Pins 85, 87, 89, 91, 93, 95, 97, 99)
The Novatel Wireless M2M Enabler IIIG module uses a single voltage source of VCC=+3.3V to
4.5V. (The exact values of the uplink currents are shown in the tables in section 5.3.1.)

The uplink burst will cause strong ripple on the voltage lines and should be
effectively filtered. We recommend that you place 1000 to 2000 µF of
capacitance as close to the modem I/O connector as possible. Do not allow the
input voltage level to drop below the minimum voltage rating under any
circumstances, especially during the uplink burst period.
Power Control (Pin 35) - (PWR_CTL)
The input is equivalent to a “phone ON-button”. A falling-edge on this Active-Low input will
switch-ON the module or switch-OFF the module after a delay*. This input has a “weak pullup” resistor inside the module. You can leave this input grounded if it does not require the
RTC Sleep Function. If it requires RTC Sleep, then you must float the PWR_CTL line to allow
the internal resistor to pull the line high.
Only an open collector/open drain device may control the Power Control signal. Driving the
Power Control signal high may interfere with the normal operation of the modem. If driving
from an external microprocessor, you can control the Power Control by driving the control pin
low as an output, then changing the microprocessor’s pin control to be an input (this will
satisfy the high impedance requirement).
The AT$OFFDLY Command controls the OFF Delay. A value of 0 disables the
PWR_CTL line from turning the module off. 0 is the default value.
To enable the module to switch-OFF via PWR_CTL, you must set AT$OFFDLY to
a value other than 0. The valid range is 100 to 1000 milliseconds.
Turning On The Enabler IIIG
You must pull the PWR_CTL line on the Enabler IIIG LOW for at least 50mS (after applying
and stabilizing Vbat) to turn it ON. Allow a minimum of 2 seconds for Vbat to stabilize before
asserting the PWR_CTL signal to turn on the modem.
Do not use a pull-up resistor on the PWR_CTL line since the line is pulled up internal to the
modem.
22
novatelwireless.com
Turning Off The Enabler IIIG
To turn the Enabler IIIG off, apply either a low pulse on the PWR_CTL line, or use a software
command (AT$OFF, see AT Command guide for further details).
Using The Power Control Signal
To power the module on/off with a switch:

External Power Control Signal (no external processor) shows a typical connection to the
Novatel Wireless M2M Enabler IIIG module in a machine-to-machine application using the
external PWR_CTL signal (when there is not an external processor controlling the power
on/off states). The RTC deep sleep functions will NOT function since the PWR_CTL pin is tied
low, the processor will never stay in a “RTC Sleep” mode. To reset the module, the power
(VBAT) must be cycled.
Figure 3-9 External Power Control Signal (no external processor)
The Power Control Signal (using external processor) figure shows a typical connection from an
external processor to the Novatel Wireless M2M Enabler IIIG module using the external PWR_
CTL signal. The Novatel Wireless M2M Enabler IIIG can be powered ON by using the PWR_
CTL signal. When using PWR_CTL, the I/O or serial lines can be at any voltage state desired.
We recommend that the I/O and serial lines be tri-stated or set low when the
GSM0308/GSM0306 is shutdown for an extended period of time to prevent any leakage
current from the processor to the modem.

Modem Power Switch
If the modem does not respond to signals on the PWR_CTL line, a power cycle (OFF-ON) of
the modem’s power is required. This condition may occur due to unpredictable network
traffic and/or unstable power sources and is more likely when the modem is running 24 hours
a day, 7 days a week.
If the host assembly does not control power to the modem, you should add a power switch to
the host assembly similar to the one shown below.
25
novatelwireless.com
If the modem's I/O lines have another source of power, the modem may not
completely shutdown/reset even with a mechanical power switch or with this
circuit implemented.
To alleviate this situation, make sure that the interface circuitry is set to tri-state
or as an input. If this is not possible, you may need additional hardware to shunt
high-impedance lines to ground during these situations.
The un-switched power source must be capable of supporting the inrush current
required by the bulk capacitance. The enable switch can be soft-started via
voltage ramp or modulation to reduce the peak current.
DO NOT USE a Modem Power Switch as a routine shutdown or reset. This
technique for shutting down the modem does not properly deregister the
modem from the network. The carrier may impose penalties if a fleet of
equipment does not follow a proper deregistration process.
Level Translation Reference Power (Pin 77)
Use pin 77 as a voltage reference source ONLY. Do not connect current loads to this pin. This
pin must be decoupled to ground with at least a 0.1 ?F capacitor at the output. Noise induced
on this pin will affect the performance of the baseband.
Low-Power Mode is entered when RTCWAKE is used to power down the modem with just
the RTC running.

independently as a user-specified function, or may be used to provide modem control and
status signals. Several examples of modem control signals are: power shutdown command,
register/deregister on network command, and transmitter disable. Several examples of
modem status signals are: registration status and ready-for-power-down status to be used
with power shutdown command signal.

RTC Sleep
In this mode, the modem is off except for its Real-Time-Clock. When put into this mode, the
modem can wake itself up at a designated time/interval. See Section 4.10 of the Enabler III AT
command manual for details
Serial Interfaces & Handshake (Pins 11, 13, 15, 17, 19, 21, 23, 25)
The pin naming for TX/RX/RTS/CTS/DTR/DSR is referenced as a DTE .The DTE device
should match their input pins to the Novatel Wireless M2M outputs and vice-versa.
Additionally, there are AT commands that may need to be executed in order to insure proper
operation. See the chart below.

Factory Set Pin Configuration
The key features of the UART in the modem mode are as follows:
16C750 compatibility
Baud rate from 300 bits/s up to 115200 Kbits/s, autobaud
Configurable data format:
l Data bit: 5, 6, 7, or 8 bits
l Parity bit: even, odd, none
l Stop bit: 1, 1.5, 2 bit(s)
Hardware flow control RTS/CTS
Software flow control using XON/XOFF characters
The Enabler IIIG module is designed to be used like a DTE device.
Default settings are 8 data, 1 stop, no parity, and auto-baud. DTR may be used to force the
modem into AT command mode from online data mode (See AT Command Document,
command AT&D). RTS and CTS may be used for hardware handshaking. DSR is always active
(connected to ground) while the modem is on. RING may be used to alert the host to a variety
of incoming calls.
The serial interface is 1.8V logic. By default, hardware handshaking (AT+IFC) is enabled. The
module will be expecting the RTS line to be low before it will transmit data. If the integrator
does not wish to use flow control, please see below for minimal serial implementations:.
For a minimal Serial implementation use one of the following two configurations:
Configuration 1:
Connect RxData (pin 15) and TxData (pin 21) to the COM port serial data lines.
DTR (pin 17) and RTS (pin 11) be pulled up through a 100K resistor if not used.
The user must set AT+IFC=0,0 to disable flow control to communicate with the modem.
Configuration 2:
30
novatelwireless.com
l
Connect RxData (pin 15) and TxData (pin 21) to the COM port serial data lines.
Tie RTS (pin 11) to CTS (pin 13), and DTR (pin 17) to DSR (pin 25) on the modem to
loopback the flow control signals
The user must set AT+IFC=0,0 to disable flow control to communicate with the modem.
Note:
It is not recommended tying DTR (pin 17) and RTS (pin 11) to ground to “spoof”
flow control. This will cause the modem to draw more current.
It is not recommended to leave that DTR (pin 17) and RTS (pin 11) unconnected.
If DTR (B12) is not connected, the default setting of AT&D0 must be maintained.
Ring Indicate (Pin 23)
The Enabler IIIG module is capable of using the Ring line to discern the type of incoming call.
The indicator can be monitored via a hardware line available on the 100-pin I/O signal
connector.
The function of the Ring line depends on the type of the call received.
When the module is receiving a voice call, the Ring line goes low for 1 second and high for
another 2 seconds. Every 3 seconds the ring string is generated and sent over the Receive
(Data Out) (Rx) line. If there is a call in progress and call waiting is activated for a connected
handset or hands free device, the Ring pin switches to ground in order to generate acoustic
signals that indicate the waiting call.
When a Fax or data call is received, Ring goes low and will remain low. Every 3 seconds a ring
string is generated and sent over the Receive (Data Out) (Rx) line.
When an incoming SMS is received, Ring indicate goes low for 1 second, then returns to a high
state. See below logic diagram.

Multi-Channel Serial Interface (MCSI) – (Pins 12, 14, 16, 18)
This port is only available in Master mode and to be used for PCM digital audio. Below are the
settings for configuring it operation and the interface specification:
Digital Audio Configuration
The default settings for the digital audio are:
Mode = Master
MCSI_CLK = 520KHz
Word Size = 16 Bits
Sync Pulse = 8KHz
Frame mode = burst
Clock edge Sync = rising edge
Configuring the MCSI for Digital Audio
The following two commands are required to set the unit up in digital audio mode:
AT$voicepth=2
This configures the EIII module to use digital audio instead of analog audio.
at$ioblks=0,1
This configures the I/O pins of the module to be used as the secondary function which is the
MCSI port. It automatically configures the direction of the pins.
Do not alter the settings for these 4 pins manually (direction, pull up or alternate
configuration) as this will stop the MCSI port working for digital audio.

Headset Detect (Pin 47)
Headset Plug/Unplug detection. This pin is used to automatically switch to the headset audio
path when enabled with AT$VSELECT=3. The device will default to handset when no
Headset is detected.
2 modes:
Module already ON (Battery connected, VRIO ON) and plug event;
Module OFF and plug event: the plug detection will be effective once VRIO is set ON
Plug and unplug detections are digitally debounced (debouncing time = 8 ms).
The jack plug detection feature is addressed through the HSDET pin. The integrated pull up,
connected to the pin, forces a high level (VBAT) when the headset load is not connected. At
jack insertion headset load connection (32 W) imposes a low level on that node (Headset left
channel): as an example HSDET = 1 mV after jack plug for VBAT = 4 V.
Input comparator threshold voltages are defined as VTlow = VBAT/2 – 100 mV and VThigh =
VBAT/2 + 100 mV, VBATmin = 3.2 V. The plug and unplug detection remains functional if
there is no signal from HSOL amplifier output (stereo path is OFF) or if there is a signal from
HSOL (stereo path is ON): maximum level on HSOL when the stereo path is ON is 1 Vp-p which
stays far enough from the comparator threshold levels VBATmin/2 – 100 mV and VBATmin/2
+ 100 mV.
38
novatelwireless.com
Jack plug detection is functional if a plug event occurs before the power up of the module or
if the plug event occurs after the power up of the module: analog detection part is always
active if the battery is connected. Detection interrupts will be generated once the VRIO
regulator is power up during the module power up sequence.
A level change on HSDET pin is sensed by a Schmitt trigger to provide a jack detection signal
to the audio digital control. The audio digital control receives the detection signal and
proceeds to a digital debouncing (time: 8 ms = 256 * 32 kHz clock periods) before sensing that
a plug event happened on the jack connector.

Subscriber Identity Module (SIM) Carrier (Pins 76,
78, 80, 82, 84)
The SIM, an integral part of any GSM terminal device, is a “smart card” that is programmed
with subscriber information:
The user information consists of an International Mobile Subscriber Identity (IMSI)
number, which is registered with the GSM provider, and an encryption Ki (pronounced
"key"). This information consists of a microprocessor and memory installed on a plastic
card.
Note: The SIM is not provided with the Novatel Wireless M2M Enabler IIIG
module. The SIM must be obtained from the GSM service provider and must be
provisioned by the operator for data and/or voice. Always take care to protect
the SIM: the GSM terminal will not operate without the SIM installed.
The SIM provides the IMSI for authentication. To gain access to the GSM network, the network
must recognize the IMSI number, and the terminal must be able to properly decrypt the data
sent by the network. The SIM also serves as a buffer for SMS messages, storing the message
for transmission until a radio link is available and buffering received messages until retrieved.

Novatel Wireless M2M provides a separate product SKU for the Enabler IIIG module with the
integrated SIM carrier.
Using A Remote SIM With The Novatel Wireless M2M Enabler
IIIG Module (PINS 76, 78, 80, 82, 84)
The Enabler IIIG module default configuration does not include an on-board SIM carrier.
The module supports the use of 1.8 V and 3 V SIM cards. The module includes a hardware
interface module dedicated to Universal Subscriber Identity Module (USIM). All baud-rates
defined in ISO 7816-3 standard are supported for high-speed transmission.
The module optionally includes an on-board SIM carrier. All other modules require a remote
SIM carrier/connector. If the module is going to be integrated using a remote SIM, the
following guidelines are provided:
To utilize a remote SIM, the integrator must provide a suitable SIM connector.
The maximum distance from the module to the remote SIM connector must not exceed
25.4 cm (10 inches).
It is recommended to have Zero resistance between the SIM connector and the module.
External ESD Protection is Required;
l 15 kV Air Discharge;
l 8 kV Contact Discharge;
The transorb must have a low junction capacitance (typically < 10 pf) such as the following

Card detect
The module provides the regulated supply voltage for the SIM-card and the circuitry to
detect the insertion or extraction of the SIM-Card in or from the mobile.
The SIMDTC is disabled by default (see AT$SIMDTC in the EIII AT Command Manual for
settings). When enabled, the SIMDTC pin has an internal pull up to Vcc and can be configured
to detect a SIM insertion when the SIMDTC is either pulled to ground or left floating.
It can configured to detect either just a SIM removal or both removal and insertion. SIM
detection is also dependent on the setting of the AT$AREG and AT+CFUN commands (see
AT$SIMDTC in the EIII AT Command Manual for more information).
When the module detects a SIM removal, it will de-register from the network. When the
module is configured to and detects a SIM insertion, it will re-register the module on the
network.
The SIM-card presence detection logic is active even when the system is in idle mode.

Remote SIM Example
ESD protection is required for all SIM sockets. A Transient Voltage Suppressor (TVS) diode
with low capacitance, typically less than 10pF, should be used. ESD protection is required for
PTCRB and GCF approval and should be located as close to the connector as possible. Signal
lines from the connector to the modem should be routed 'through' the pad of the diode,
rather than a 'T' branch. Decoupling capacitance on SIM_VDD will be required, and should be
placed as close to the SIM connector as possible. The value of the required capacitor will vary
by design, and will typically be below 0.1uF. The SIM electrical tests will be conducted during
the PTCRB and GCF approval process. Experimentation of the capacitance value may be
required to pass these tests. Factors affecting the capacitance of the SIM_VDD line include:
trace length, capacitance of the TVS diode, and physical placement of the capacitor.

General Design Guidelines For Using Novatel
Wireless M2M GSM Modules
The following guidelines are provided in an effort to allow Enabler IIIG module users to
successfully implement their PCB layout to obtain the best performance. This includes the
lowest possible EMI emissions, maximum thermal conduction, mechanical integrity, and voice
quality. The Enabler IIIG module is a very compact, high performance design, yet it is easy to
interface into the final product. In order to realize its full potential, designers should pay close
attention to ground structures, the routing of RF and Digital traces, and the size of the power
supply lines.
Warning: These design tips are strictly guidelines and are not meant to be a
complete list of items that guarantee actual performance. Each application is
different and may require variation from these guidelines, however, care should
be given to utilize these sound engineering principles whenever possible
Advanced Tips For An RF Friendly Layout
To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is
recommended that all metal tabs on the GSM module shield must be soldered down onto a
continuous ground plane that runs under the entire module. Ample ground vias should be
provided around the metal tabs to create a low impedance ground. It is recommended to
minimize the number of I/O and power traces and vias under the GSM module to allow for as
much ground plane as possible. An example of a good ground structure and pad layout is
shown below in Figure 1.
45
novatelwireless.com
Figure 4-1 Example of good ground plane for GSM modules
Thermal Relief
Because the ground plane acts as a large heat sink, it can affect the solderability of
components. A common method to reduce this effect is to use thermal relief around the pad
in question. However, great care must be taken when using thermal relief for high current or
high frequency applications
For example, a large thermal relief like the one shown in Figure 2 can serve the purpose for
general applications such as low current, low speed data lines, DC connections and audio
frequency applications. However, such thermal relief structures should be avoided for
applications where high current and/or high frequency is involved, such as those using the
Enabler Module. Depending on the frequency of operation, the long narrow thermal relief
traces between the pad and the ground plane act like an RF choke. These RF chokes become
higher impedance at harmonics of the fundamental frequency making it problematic for high
frequency suppression. This can make it difficult to pass type approval testing.

Figure 4-2 Example of a POOR RF Thermal Relief
If thermal relief is necessary, it is recommended that you use short, fat traces similar to those
shown in Figure 3. This will still provide a solderable connection, while providing a better RF
connection. Making them shorter also allows for a more continuous ground plane due to less
copper being removed from the area. It is also recommended to have ground vias around all
thermal relief of critical ground pins such as the five Enabler shield tabs.
47

Figure 4-3 Example of a GOOD RF Thermal Relief
Antenna And RF Signal Trace
The PCB trace that feeds the RF output port must be designed for a 50 ohm characteristic
impedance, coplanar, or routed into internal layers to keep the top layer continuous around
and underneath the Enabler module. Ample ground vias should be provided around the RF
contacts, the RF trace and launch pad. If possible, keep I/O and power traces away from the
RF port. This includes traces running parallel or orthogonal to it. Thermal relief should not be
used on the antenna output port ground pads. The designer must pay close attention to the
size of the pad and thickness of the dielectric beneath the signal pad and trace. Most PCB
manufacturers can adjust the trace width to maintain 50 ohms impedance if the traces are
identified and instructions are included on the FAB drawing. This service is typically provided
at no or minimal additional cost.
For minimum RF emissions due to the fundamental frequency of operation, the Enabler
module works best with an antenna load that has a VSWR of 1.5:1 or better. The antenna
should not have gain at the harmonic frequencies, otherwise, the conducted harmonics could
get amplified to a point where the product no longer passes type approval. However, for
48
novatelwireless.com
applications where antenna quality is less than ideal, it is recommended to have a low pass
filter (Pi structure with N=3) in the RF path to the antenna. This is a secondary plan should
there be a need to lower harmonic levels at frequencies above the PCS band. The pad
structure may also be used to match the antenna load impedance, if required. If it is not
needed, a capacitor of low reactance may be used to bridge the Pi structure.
The RF cable going between the Enable module and the antenna is very lossy, therefore, the
length of this cable should be kept as short a possible.
VBAT Input
The Enabler Vbat input can have a relative high current draw that can fluctuate rapidly,
especially when transmitting at max power and burst mode. The Vbat interface must be
designed to provide the required instantaneous voltage and current with minimal voltage
droop. This includes both sufficient bulk decoupling capacitance as well as adequate layout
provisions.
When laying out the connections to the Enabler interface connector, it is tempting to use
traces of the same width as the connector pins. However, this is a very compact connector
and traces of that width will not have sufficient copper. Similar to the discussion on thermal
relief, the use of narrow traces to connect the Vbat pins to the source voltage can act like a
high impedance and cause a significant voltage droop when higher currents are required as
shown in Figure 4.
49
novatelwireless.com
Figure 4-4 Example of Vbat Voltage Droop
If the Vbat drops too low, the Enabler modules will reset. To minimize the trace loss, it is
suggested to use a larger trace that spans several pins as shown in Figure 5. Any concern
about solderability can be mitigated by using solder mask with cutouts for the individual pins
as shown by the blue lines in the figure. The layout should provide sufficient trace width over
the entire trace from the Enable modules all the way to the source of the Vbat voltage. Any
transitions between layers for this trace should utilize multiple vias.
Since even the best layout will have some impedance from the source to the Enabler module,
sufficient bulk decoupling capacitance is required at the Vbat input to the Enabler module. It
is suggested to use at least two 1000 uF, low ESR, tantalum capacitors located very close to
the Enabler interface connector Vbat pins. Any thermal relief used on these capacitors should
comply with the information given above in order to provide the lowest impedance possible.
The grounding of these capacitors is critical. Therefore, it should be a low impedance and
should utilize multiple vias to the internal ground plane close to the capacitor as well.

GSM/GPRS supports many optional services and modes. The Novatel Wireless M2M Enabler
IIIG module supports the following GSM/GPRS services:
Circuit-switched data
Short-Message Services (SMS)
Class B GPRS Functionality
Voice communication
52
novatelwireless.com
Enabling The Transmission Modes For The
GSM/GPRS Services
Each of the GSM/GPRS services has two modes that can be enabled separately:
Mobile-originated (MO): allows the making of a service request (such as, making a telephone
call or sending an SMS)
Mobile-terminated (MT): allows receiving a service request (such as receiving a telephone call
or an SMS)
Note: Contact your local GSM operator to ensure that the services and modes
have been provisioned for the SIM
Voice Communication
The Novatel Wireless M2M Enabler IIIG module has full voice capabilities, provided the
necessary connections have been made for the speaker and microphone pins on the 100-pin
I/O connector. The Novatel Wireless M2M Enabler-IIIG AT Command Set Reference GSM0308AT001 has the entire list of commands that can be used to control the voice
functionality. The quick start guide in this manual provides a basic command set that can be
used to initialize and test the voice functionality.
The Novatel Wireless M2M Enabler IIIG module supports four vocoder compression
algorithms for voice communication: Full-Rate (FR), Enhanced Full-Rate (EFR), Half-rate (HR)
and Adaptive Multi-rate (AMR).
Circuit-Switched Data
In this mode, the Novatel Wireless M2M Enabler IIIG module supports both of the connection
modes of transmission that are provided by GSM:
Non-Transparent mode delivers a constantly low error rate but with a non-guaranteed
throughput or delay. The Non-Transparent service provides a performance that is closest to
using a modem over a fixed Public Switched Telephone Network (PSTN) line.
53
novatelwireless.com
Note: All GSM service providers may not support transparent mode. In those
cases, the Novatel Wireless M2M Enabler IIIG module can be configured to switch
automatically to Non-Transparent mode. This capability depends on the settings
in the AT+CBST command.
SMS: Short Message Services
Short Message Services (SMS) is a feature-rich GSM service. The Novatel Wireless M2M
Enabler IIIG module can perform the following tasks:
Sending and receiving binary messages of up to 160 characters (7-bit characters)
Sending and receiving text messages of up to 140 bytes (8-bit data)
Submitting a SMS Protocol Data Unit (PDU) to a SMSC (Short Message Service Center)
and storing a copy of the PDU until either a report arrives from the network or a timer
expires
Receiving a SMS PDU from a SMSC
Returning a delivery report to the network for a previously received message
Receiving a report from the network
Notifying the network when the module has sufficient memory capacity available to
receive one or more SMS messages (after the module had previously rejected a
message because its memory capacity was exceeded)
Provisioning The SIM
The SIM can support optional features or services. Most operators typically configure the SIM
to send/receive voice calls and to receive SMS; however, some may require an additional tariff
to enable the SIM to send SMS. The transmission of circuit switched and GPRS data are also
additional services that may be required to allow the service:
Mobile-originated (MO): allows making a service request (such as, making a call or
sending an SMS)
Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone
call or an SMS)
It is imperative for the Novatel Wireless M2M Enabler IIIG module that the SIM be configured
for the optional services that are required for the application.
GSM Services Supported By The Novatel Wireless
M2M Enabler IIIG Module
The Novatel Wireless M2M Enabler IIIG module supports four GSM services (modes of
operation) that must be enabled by the operator:

Initialization (AT Command Interface)
In the GSM vocabulary, a call from GSM mobile to the PSTN is called a "mobile-originated call"
or "outgoing call". A call from the fixed network to a GSM mobile is called a "mobileterminated call" or "incoming call."
In the following examples, “Entry” refers to the application. The following convention
describes the direction of the data exchange:
The data exchange from the customer application to the module is designated as: Entry
The data exchange from the module to the customer application is designated as:
Response
Note: With the exception of the +++ command (Online Escape Sequence), all
commands must be preceded by the AT attention code (or command prefix) and
terminated by pressing the  character.
In the following examples, the  and  are intentionally omitted for
clarity and space.
58
novatelwireless.com
Initial Response To The AT Command
After power is applied to the module, the module performs a power-up self-test. The self-test
completes within one (1) second. When queried with the AT command, the module responds
with one of the following result codes:
OK signifies that the module is ready, that it correctly interprets the AT command, and
that it has executed the command.
ERROR signifies that the module does not understand the command or that the
command is invalid.
Entry
AT
Response OK Command valid: module is ready
The module must be in AT Command mode when any command is entered (with the
exception of the online escape sequence). Commands entered when the module is in On-line
mode are treated as data, and are transmitted as such to the receiving module. (i.e. If the
module is in PPP or SLIP mode, AT commands cannot be entered.)

Integration And Testing
Integrating the Novatel Wireless M2M Enabler IIIG Module
61
novatelwireless.com
The Novatel Wireless M2M Enabler IIIG module has been designed to minimize the amount of
time required for integration and testing the application. By being fully certified by the
appropriate bodies, the Novatel Wireless M2M Enabler IIIG module provides seamless
integration into the GSM network.
The integration issues for the application can be narrowed to the utilization of the AT
commands and the use of the GSM functionality. Coverage and signal quality may be
evaluated by using the RSSI commands. Additional network information can be determined
by using AT commands.
Integration of the GPRS Packet capabilities is more complicated than using AT command
sequences to initiate the connection and begin transferring data. The following Application
Notes should be used to integrate the GPRS packet capabilities:
GSM0000AN001 - Enabler-G PPP Configuration for Windows 98
GSM0000AN002 - Enabler-G PPP Configuration for Windows 2000
GSM0000AN008 - Enabler-G PPP Configuration for Windows XP

GSM0000AN005 - Enabler-G Automated Network Connection Configuration and Use
Integrating The Novatel Wireless M2M Enabler IIIG
Module
Note: Generally, all interfaces that are externally available to the end user need to be ESDconditioned and terminated in some way. Many of these interfaces should not be connected
with power applied.
At the highest level, this is done using some type of GSM test equipment (such as, Racal
6103E), a computer, and a serial interface tester. The GSM test equipment must be able to
simulate a GSM call and measure the key parameters related to the module.
Additionally, the serial interfaces and some minimal SIM functionality can be verified by
sending AT commands to the Novatel Wireless M2M Enabler IIIG module.
All of these conditions need to be verified at ambient as well as extreme conditions.
As part of integration, each of the following interfaces must be verified:
